Abstract
A kind of chemical waste liquid negative-pressure recovery device, comprises well heater, vaporizer, condenser, liquid seal trough, it is characterized in that: also comprise the water-ring pump unit and small-sized lime set surge tank that vacuumize; Described well heater, vaporizer, condenser is connected successively with liquid seal trough; Described base of evaporator outlet connects discharging pump; Described condenser connects small-sized lime set surge tank, and small-sized lime set surge tank is provided with liquid level switch at tank inner top sidewall; Described well heater, vaporizer, condenser is provided with temperature, pressure transmitter; Described device adopts PLC automatic control system.The utility model is by replacing vapo(u)r blasting pumping set with water-ring pump unit, and solve because adopting negative pressure leaching technology mode to carry out devil liquor recovery in actual production, there will be recirculated water vaporized many, cooling water outflow is excessive, the problem of the weak effect recycled.
Description
Technical field
The utility model relates to industrial effluent recovery technology field, especially relates to a kind of chemical waste liquid negative-pressure recovery device.
Background technology
In modern industrialization is produced, if undressed waste liquid arbitrarily discharges, not only environment is exerted an adverse impact, even can destroy ecology and cause the waste of resource.The process how effectively carrying out industrial effluent little by little obtains the attention of increasing industrial production enterprise and continuous to carry out transformation to liquid waste treating apparatus perfect.
In prior art, the process for industrial effluent adopts negative pressure concentration and evaporation technique more.Negative pressure evaporation principle is by containing metal-salt, the aqueous solution of hydrogenchloride solute, heat under vacuum conditions, the solute of solubility in solution is evaporated together with water, cooling water condensation is utilized by condenser, formation can return the hydrochloric acid that workshop is reused, along with the volume of solution reduces, in solution, the concentration of not volatilizable solute metal salt increases, form the supersaturated solution of metal-salt, then by cooling, reduce the solubleness of solution, under solution hypersaturated state, that a part of metal-salt is with the crystal state crystallization of water-containing crystal thing, reach being separated of solute and solvent in solution.
In actual production, enterprise, is difficult to rearrange because the vaporizer and condenser of giving waste liquid heating and cooling fix in production equipment district when carrying out scrap build.And limit due to the height of existing equipment, cause the fluid-tight pipeline potential difference of phlegma inadequate, fluid-tight requirement cannot be arrived, so adopt Vacuum filtration device carry out solid-liquid separation and select vapo(u)r blasting pumping set as vaccum-pumping equipment.But adopt this kind of negative pressure leaching technology mode to carry out devil liquor recovery, there will be recirculated water vaporized many, cooling water outflow is excessive, the weak effect recycled.
Summary of the invention
For the problems referred to above, the utility model improves on original production unit, vapo(u)r blasting pumping set is instead of with water-ring pump unit, and adding corresponding device, concrete technical scheme is: a kind of chemical waste liquid negative-pressure recovery device, comprises well heater, vaporizer, condenser, liquid seal trough, is characterized in that: also comprise the water-ring pump unit and small-sized lime set surge tank that vacuumize; Described well heater, vaporizer, condenser is connected successively with liquid seal trough; Described base of evaporator outlet connects discharging pump; Described condenser connects small-sized lime set surge tank; Described device adopts PLC automatic control system.
Further, described small-sized lime set surge tank is provided with liquid level switch at tank inner top sidewall.
Further, the opening for feed place of described well heater is provided with under meter, and opening for feed connects fresh feed pump.
Further, described well heater, vaporizer, condenser is provided with temperature, pressure transmitter.
The beneficial effects of the utility model are:
1. device of the present utility model transforms on existing device basis, completes productive capacity when not changing original production unit position, has the advantage that operation running expense is low;
2. to have vaporization efficiency high for this waste liquid evaporation device, can continuous and stable production, simple to operate, adopts full negative pressure system to ensure that clean and safe production, reduce workshop condition and pollute;
3. device adopt PLC automatic control system, operator are used more safe and simple, also reduce lime set amount, reach water coolant good recycle effect.

1. well heater, 2. vaporizer, 3. condenser, 4. liquid seal trough, 5. water-ring pump unit, 6. small-sized lime set surge tank, 7. discharging pump.
Embodiment
Specifically implement to be illustrated to the utility model in conjunction with the accompanying drawings and embodiments.
As shown in drawings, a kind of chemical waste liquid negative-pressure recovery device that the utility model provides, comprises well heater 1, vaporizer 2, condenser 3, liquid seal trough 4, also comprises the water-ring pump unit 5 and small-sized lime set surge tank 6 that vacuumize; Described well heater 1, vaporizer 2, condenser 3 is connected successively with liquid seal trough 4; Described vaporizer 2 outlet at bottom connects discharging pump 7; Described condenser 3 connects small-sized lime set surge tank 6; Described device adopts PLC automatic control system.
Further, described small-sized lime set surge tank 6 is provided with liquid level switch at tank inner top sidewall.
Further, the opening for feed place of described well heater 1 is provided with under meter, and opening for feed connects fresh feed pump.
Further, described well heater 1, vaporizer 2, condenser 3 is provided with temperature, pressure transmitter.
Water-ring pump unit 5 connecting fluid sealing groove 4, the negative maintenance negative pressure state of liquid seal trough 4, the condenser 3 be connected with liquid seal trough, vaporizer 2 also all keeps negative pressure state, and then improves the volatilization efficiency of vapo(u)rization system.
